similar to: Increasing mail_max_userip_connections and sys resources

Hi, A couple of questions rather than a problem for once! We've got our Dovecot server running smoothly now apart from our MD. He's having problems with mail_max_userip_connections. He has 3 (Phone/Laptop/Tablet) items that all connect to the server at about the same time. Which means he's frequently running over the max_userip_connections. My questions are: Is there

Hi, I set mail_max_userip_connections in our IMAP configuration to mail_max_userip_connections = 10 to allow users 10 parallel connections. It seems that this also limits the amount of parallel connections from one IP but different users?! Our users mostly accessing the IMAP server by a webmailer or proxies. Thus, all users (>10000) come from only 5 different IP. However, I got a lot of

What is the appropriate setting for mail_max_userip_connections ? My POP3 connections seem to be mostly 1 at a time, but my IMAP connections are often 3 per user per IP. Is this appropriate? If I change the IMAP setting to mail_max_userip_connections=1 will it break things for the user? I am trying to improve this situation: > ps auxwww | grep "imap " | wc 237 3080 22400

Hi, has anyone seen this issue before as I have not. I'm a long time dovecot user and I don't see anything in the config that should cause this. The mail.log gets hit a lot of times with this same log message: dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections) I have noted that it is more evident when I try to mass delete many

Hi, I'm having a problem with a webmail client trying to open multiple IMAP connections with dovecot, and hitting a cap. I see from the error logs from this program that it's hitting the mail_max_userip_connections cap, but I'm not seeing this value as defined in the dovecot.conf file. Would this automatically get set to a certain value by default if it's not present? Thanks,

Hi Sometimes, I hit mail_max_userip_connections limit. As far as I know I'm the only person that does, but I would like to find out why before someone else hits the limit. Is there a command available that can list the connections per IP? I'd like to find out which client is causing this. Or do you have a better suggestion? Should I just raise the limit (it's still at the default

Hello, Can the above setting be applied on a per user account basis? I thought that maybe something like per account quotas might be a possible method but not sure. Thanks.

Hello. Is still true that mail_max_userip_connections cannot be overriden in userdb query? Want lower global and raise for some logins. https://www.dovecot.org/pipermail/dovecot/2017-July/108520.html -- Arkadiusz Mi?kiewicz, arekm / ( maven.pl | pld-linux.org )

Hi, The documentation at https://wiki.dovecot.org/UserDatabase/ExtraFields states that "It's possible to override settings from dovecot.conf", as well as the following: > If you want to override settings inside sections, you can separate the > section name and key with '/'. For example: > > namespace default { > inbox = yes > separator = .

Hi I'm using Dovecot version 1:1.2.15-7 installed on Debian Squeeze via apt-get..

Hi All, I am new here, please warn me If I am not following proper etiquette of this mailing list. I am breaking my head, regarding why libvirt is defining multiple CPU sockets when I increase the vCPU count. As and when I increase the vCPU count in libvirt guest XML, it is increasing the CPU sockets in qemu instance. " -smp 4,sockets=4,cores=1,threads=1 " instead " -smp

Hi Daniel, Thanks a lot for the quick and detailed explanation. Please see my another query below. >>In normal usage, the guest vCPUs will be floating arbitrarily across any >>host physical CPUs.

Hi, Is there any patch available for increasing routing tables from 256 to higher number for Fedora Core 3 and above. Regards, Prasad.

Hello. I have a wireless system (link bandwidth = 700 kbit/s) that transmits realtime udp video data and other various tcp protocols. I don''t care if I lose the occassional udp packet but i''d like all of the tcp traffic to get through. I''m thinking that a Generalized RED will give me the best results: 2 queues, one for TCP (very low probability of dropping) and one

I''m wondering what other folks think of Dojo (0.1 just released), MochiKit, and some of the other js frameworks relative to prototype/scriptaculous (p/s). P/S seems to have broader support although I''m not sure about IE 5.5 in the other frameworks. A second question is related. I''ve got some AJAX working with prototype + behaviour, and I''m building in refresh
